She also questioned the "motivation to be provocative with the Iranians."

"What is their motivation to be provocative with the Iranians? Why did the president turn his back on the Iranian nuclear agreement?" she said, according to a transcript. "What's the logic except some other issue — that it was negotiated by President Obama?"

"We had so many national security experts, whether they were ambassadors, generals, admirals and all the rest, supporting the agreement," she added.
